Problems solved by technology

[0003] First, a defrosting cycle needs to start and stop the compressor twice, which consumes a lot of energy and has a great impact on the power grid. Frequent starting and stopping will increase the failure rate of the compressor
[0004] Second, it takes about 5 minutes to start and stop the compressor, and change the direction of the four-way valve. The whole defrosting process takes about 12 minutes. There is no heating output, which will seriously affect the heating effect of the heat pump, reduce the heating capacity, and reduce the comfort of the air conditioner

Abstract

The invention provides a non-stop defrosting system and an air-conditioner. The non-stop defrosting system comprises a compressor, a first four-way valve, a second four-way valve, a first three-way valve, a second three-way valve, a first outdoor heat exchanger, a second outdoor heat exchanger, an indoor heat exchanger, a first throttling device and a second throttling device. According to the technical scheme, each outdoor heat exchanger is composed of two parts and the flowing direction of refrigerating fluid can be controlled through one four-way valve and one three-way valve; after the outdoor heat exchangers are frosted, compressor non-stop and indoor unit ceaseless heating can be achieved through the alternate defrosting mode of the two outdoor heat exchangers, heating operation efficiency of the air-conditioner is greatly improved, and thus the heating comfort of the air-conditioner is increased; and meanwhile, the problem of frequent start and stop of main electric parts like the compressor is effectively avoided, the defrosting speed is increased, and therefore the effect of reducing energy consumption is achieved, the failure rate of the main electric parts like the compressor can be better lowered, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a non-stop defrosting system and an air conditioner. Background technique [0002] At present, the defrosting method commonly used in the heat pump (air conditioning) system is: the compressor is stopped, then the four-way valve is reversed, and then the compressor is started to defrost. The specific defrosting process is: enter the defrosting mode - stop the compressor - change the direction of the four-way valve - start the defrosting of the compressor - stop the compressor - change the direction of the four-way valve - start the compressor to heat up - - Anti-cold wind - end the impact of defrosting and normal heating. This defrosting method has the following disadvantages: [0003] First, a defrosting cycle needs to start and stop the compressor twice, which consumes a lot of energy and has a great impact on the power grid. Frequent start and stop will increase the...
